Abstract: A method of fabricating self aligned static induction transistors. The method comprises fabricating an N silicon on N⁻ silicon substrate having an active area. A guard ring is formed around the active area. An N⁺ polysilicon layer is formed that comprises source and gate regions. An oxide layer is formed on the N⁺ polysilicon layer. A second polysilicon layer is formed on the oxide layer. A second oxide layer is formed on the second polysilicon layer which is then masked by a self aligning mask. Trenches are etched into the substrate using the self aligning mask and gate regions are formed at the bottom of the trenches. A first layer of metal (gate metal) is deposited to make contact with the gate regions. A layer of photoresist is deposited and planarized, and the first layer of metal is overetched below the top surface of the trench. Plasma nitride is deposited and planarized, and a polysilicon mask is deposited over the planarized layer of plasma nitride. The polysilicon mask is etched to expose the gate metal disposed on the field. A second layer of metal is deposited to make contact with the source and gate regions. A passivation layer is formed, and interconnection pads are formed that connect the first and second layers of metal. The present method employs a single minimum geometry trench mask. The key features of the transistor are defined by the trench mask and related processing parameters. Because of the self alignment achieved by the present invention, the number of channels per unit area is higher, which results in higher transconductance. In addition, some of the parasitic capacitance is eliminated by the present invention, resulting in faster operational speed. The variable sidewall trench oxide thickness allows fabrication of static induction transistors with higher or lower breakdown voltages according to the thickness that is chosen, and for a more graded P gate junction.

Abstract: A perforator for making perforations in a continuous film which is thereafter cut into individual filmstrips having variable lengths. A die set unit of the perforator has a plurality of punches and corresponding dies which are respectively arranged along the continuous film. The die set unit performs die-punching  N  times (N = 1, 2, 3 ...) in every first section having a variable length  Lx , and the measuring feeder transports the continuous film by a first length after each of (N - 1) times die-punching and by a second length after the last die-punching for every first section. The first length is given as Lx / N, and the second length corresponds to the first length plus the length  L2  of a second section disposed alternately with the first section along the continuous film. In alternative, the die set unit is constituted of first to  n th die sets aligned in this order from downstream in the film transporting direction. The  i th die set of the die sets has a number  Gi  (i = 1, 2, ... n) of punches as a segment of the total punches. The first to  i th die sets are simultaneously activated to perform die-punching. The number  i  is selected depending on the number  F  of frame exposure locations to be provided in each individual filmstrip.

Abstract: A particle image analyzing apparatus of high classifying accuracy and high efficiency in which a criterion for determining whether fine classification is required or not can be set for every facility such as hospital, or the like. A rough classification unit executes rough classification of particles and supplies results of the rough classification to a fine classification necessity determination unit. The necessity determination unit compares the results of the rough classification with reference values stored in a reference value storage unit and determines from the comparison whether every sample is normal or abnormal to thereby determine whether fine classification is required or not. The reference values stored in the storage unit can be changed in accordance with the subject of examination through an input/output control unit from a keyboard. When the determination unit makes a decision that fine classification is required, the determination unit gives an instruction to an image processing control circuit to execute fine classification. 
Characteristic parameters for fine classification are supplied to a fine classification unit on the basis of the control instruction of the control circuit. Then, fine classification is executed, so that results of the fine classification are supplied to the determination unit. The determination unit stores the images of the particles in an internal image memory and displays the results of the classification in accordance with an instruction given from the keyboard.
